The Marlins have long lacked left-handed power. Since Mike Jacobs did it in 2008, no left-handed Marlin has eclipsed 30 home runs in a single season. However, that soon might change as Joe Mahoney and Christian Yelich, both lefties, have brandished some hefty power this spring.
In Spring Training, Joe Mahoney, who was picked up off waivers from the Orioles in the off-season, is getting substantial playing time at first base with Logan Morrison sidelined, recovering from knee surgery. It is possible that Morrison will not even be ready for Opening Day, opening the door for Mahoney. In just 14 at-bats this spring, he has 5 hits, 2 homers, and 5 RBI.
Christian Yelich, who was a first round draft pick in 2010, is a non-roster invitee to Spring Training. He was a first baseman in high school, but the Marlins have converted him to an outfielder. Yelich has 6 hits in 13 at bats, with a home run and 3 RBI this spring. He will most likely start the year at AA Jacksonville, but he is a viable candidate to be called up during the season, or at least in September.
Greg Dobbs, Logan Morrison, and Chris Coghlan are the other lefty power threats currently on the roster.
